GRAIN-SCALE.

EPECIFIEOATION forming'part of Letters Patent No. 3493257, datedSeptember 21,1886.

Application filed January 13, 1886.

T0 (tZZ whom it may concern.-

Be it known that I, KAsrEn H. Senarnn, ot'Linns Hills, Lincoln county,Missouri, have made a new and useful Improvement inG rain Scales, ofwhich the following is a full, clear, and exact description.

The present construction is an improvement in that class of grain-scaleshaving a weighinghopper adapted to be balanced to receive any Iixedweight of grain, and when the desired amount has been admitted thereiutoto drop, and thereby cause the bottom of the weighing hopper to open andthe grain to be discharged from the hopper.

The improvement consists in the weighing hopper having compartments intowhich alternately the grain is received and thence discharged, incombination with the means for directing the admission of the grain intothe compartments and its discharge therefrom, substantially as ishereinafter set forth and claimed.

In the annexed drawings, making part of this specification andexhibiting the improvement, Figure 1 is a side elevation of the scale.Fig. 2 is an end elevation, the parts being as in Fig. 1. Fig. 3 is viewsimilar to that of Fig. 1, but showing the weighing hopper dropped andthe opposite compartment-bottom opened; and Fig. rt is a verticalsection on the line st i of llig. 2.

The same letters of reference denote the same parts.

The present graiuseale can be used by itself or in combination withother mechanisms such as employed in mills using grain, or such as areused in handling or treating grain. In the present instance theweighing-hopper A is shown supported by the frame 13, the frame being inthe form of the uprights I) I), arranged at opposite sides,respectively, of the weighinghopper, and connected therewith as follows:

0 represents a scale-beam, whose outer end, 0, is in the form of anordinary scalebeam, and whose opposite end is forked, the forks c c, bymeans of the knife-edges 0, being held and adapted to rock in bearingsZ) in the uprights I), and the weighing-hopper, by means of theknife-edges (1 ,being h ung in the forks c c,and so that b Y means of awei ht I) the wei hin D 7 7 O b Serial No. 185,356. (No model.)

hopper can be weighted to receive the desired quantity of grain beforeit shall drop and bear down the forked end of the scale-beam. Theweighing-hopper at its upper end has an opening suitably shaped to admitthe grain to be weighed.

The weighing-hopper, by means of a partition, a, is divided into twocompartments, (6 a, Fig. 4. A valve, a, is jointed to the partition atits upper end, and the valve, as indicated by its two positions, shown,respectively, in the full and in the broken lines in Fig. 4, can beturned upon its hinge so as to form an opening into one, a, of thecompartments, and meanwhile close the entrance into the oppositecompartment, a", or to close the entrance into the compartment a andopen that into the compartment a"that is, when the valve is turned intothe position of the full lines, Fig. 4-, the grain drops through itsopening a into the compartment a, as indicated by the arrows shown inthe full lines, and when the valve is turned the opposite way the grainfalls through the opening a into the compartment 0 Each compartment hasits own bottom. That, a", of the compartment a is hinged at the point a,and the bottom a of the compartment a is hinged at a The two bottoms a eare connected, so that when one of them is opened the other is closed.This is ell'ected as follows: E represents an arm that is fastened to anextension, a", of the shaft a, to which the valve a is attached. Thisarm, at its ends, respectively, and by means of the swinging rods F G,respectively, is connected with the bottoms of a Then when one-say thebottom w"is depressed by the weight of the grain upon it, that end ofthe arm E with which that bottom is connected is drawn down with thebottom, and the valve a is turned with the arm E, and so as to deflectthe grain into the compartment a, to rest upon the bottom a and whenthat bottom a is depressed the arm E and valve a are turned in theopposite direction. The bottoms open when the fixed weight of grain hasaccumulated upon the bottom. The weighinghopper at the same time alsodrops. The arm E has an extension, 0, extending upward. It operates inconnection with a fixed shoulder, H. As long as the hopper is in itselevated position, the shoulder, as shown in Figs. 1, 2, is against oneside of the extension e, and the arm E in consequence cannot be moved;but when the weighing-hopper drops the extension 6 is no longer held bythe shoulder H, and the arm E and valve a are free. As each compartmentthen is filled, the weighing-hopper drops, the bottom of thatcompartment which has been filled opens, and the grain therein isdischarged from the and by reason of the opening of the bottom the valvea is changed and the bottom of the opposite compartment is closed.Immediately following this the hopper rises again, bringing the oppositeside of the extension 6 against the shoulder H, again confining the armE and valve a until the lastreferred-to compartment is" filled with thegrain, and so on, directing the grain first through one and then throughthe other of the compartments. The shoulder H may be supported in theposition shown by any suitable means-as, for instance, by means of thearm I, which in turn is supported from the frame 13. The arm J serves tokeep the hopper vertical as it moves upward and downward, as described.A special advantage derived from'this construction is, that the flow ofthe grain into the hopper is, by the means described, at once deflectedto and fro into one compartment and the other, so that the grain isaccurately weighed.

compartment, and with The movementof the hopper as it falls can beregistered in any desirable manner.

I am. aware that it is not broadly new in devices of this description todivide the hop- 5 per or grain-receptacle into two parts, each having ahinged bottom, and said bottoms provided with rods connecting with thevalves at the lower end of the induct to the hopper, whereby the graincan be automatically fed into one chamber of the hopper so soon as theother is filled. r I claim- The weighing-hopper having a valve in itsopening, and two compartments, and the hinged bottoms at the lower endof the compartments, respectively, in combination with the swinging rodsF and G, pivoted at their lower ends, respectively, to the hingedbottoms a and a of said compartments, and at their upper ends, onopposite sides of the arm E, fastened to the shaft a of the valve-ainthe opening of the hopper, said arm having the extension 0, the fixedshoulder H, the frame B, the beam 0, and the weight D, as described.
